Rember boys and girls.. when reading an EIGRP question, any positive-sounding description is automatically EIGRP. "Quickly computes new paths?" - MUST BE EIGRP! "Can load-balance unequal cost LB?" - MUST BE EIGRP! Only CISCO DESIGNS THE BEST PROTOCOLS

Incorrect, OSPF quickly computes new paths. EIGRP should have a backup path (feasible successor) at the ready in case of a link failure, so it doesn't need to compute anything upon link failure. EIGRP in this question uses the DUAL algorithm (OSPF uses Dijkstra algorithm), and maintains an alternative path (feasible successor), so "quickly computing a new path" is left for OSPF. You can make sarcastic remarks about how "awesome" Cisco is, just make sure you're giving the correct information when you do so. There's enough confusing questions on the ENCOR test already.

Provided answer is correct, But, EIGRP is considered to have faster convergence times than OSPF, particularly in the case of a link failure, and EIGRP can converge within a few hundred milliseconds, while OSPF can take a few seconds.

JackDRipper

Answer is correct. "Quickly computes new path upon link failure". True for OSPF as it needs to re-compute and LSAs generated upon a link failure. On the other hand, EIGRP is always ready with the 2nd-best route (ie. Feasible Successor), if available.

On the other side, OSPF has full picture of the network. EIGRP needs to send Query if can't find the way.

CCNPWILL

Correct... but they should swap out the answer for OSPF.. like uses concept of areas.. something obvious and specific to OSPF... they both ' quickly ' reconverge networks =\. thats what screwed this question honestly.

This question is outdated. OSPF now has loop free alternate fast reroute capabilities that rival EIGRP with a feasible successor. Not that OSPF cannot always converge fast, like when an area has 50 nodes and all have to run the Dykstra algorithm. Likewise, EIGRP without a feasible successor may take a while to converge, especially if it gets stuck in active. https://networklessons.com/cisco/ccie-routing-switching-written/ospf-loop-free-alternate-lfa-fast-reroute-frr
